In this talk, I will talk about our recent work on bandwidth allocation problem in two projects: TCP friendliness and P2P streaming.
While the current definition of TCP friendliness has enabled a wide variety of traffic control protocols other than TCP, it still considerably restricts the design space of TCP friendly traffic control protocols. In this project, we propose a new class of TCP friendliness definitions, called Stochastic TCP Friendliness, which greatly expands the design space of TCP-friendly traffic control protocols, while still effectively maintaining the desired stability and fairness of the Internet.
Most of the commercial P2P streaming systems support hundreds of channels and are referred to as multi-channel P2P streaming systems. Recent research studies have proposed several bandwidth allocation methods to improve the system streaming quality by enabling cross-channel cooperation. In this project, we study a fundamental problem: which bandwidth allocation method can achieve the desired streaming quality with the lowest implementation complexity?
